Lockers (Posted on 2002-12-06) Difficulty: 2 of 5
There is a wall with 1000 closed lockers on it. A person walks down the hall opening every other locker. Then the next person opens every 3rd locker. The next opens every fourth locker. The next every fifth locker.

Once this has been done, how many lockers are still closed?

See problem "OPENING DOORS" -- this is (almost) a duplicate.
